The stock 307 gears are probably why my Jeep stalls out so much when i'm climbing, right?? A 410 should work alot better???

4.10 or 4.56 if you want to go bigger in the future.

They sure aren't helping you any in 4wd or on big inclines. :D

Did the 6-speeds really come with 3.07's?

mine did and they suck.

i want some 4.56's with my 32's.

Serious? My 3.07's with 32's ain't bad at all... but I have an auto so that might be the reason, even though its a 3-speed.

How hard is it to swap out gears? Is it something I'd want a pro to do or can a shade tree do it??

4.56's would take you from a 33:1 to a 49:1 crawl ratio which would help great deal. (assuming with the 6spd your 1st gear is 4:1)

With 4:56's would I still be ok on the hwy in 6th gear? (would the rpm stay prety low for hwy driving?)

the difference between 3.07 and 4.56 is about 50%. the RPM will be about 50% higher after regearing. you´ll be able to use your 6th gear again. now the RPM in 6th gear should be that low that you cant hold the speed at highway speed.
and your gas mileage will become better.

when you regear you should think about installing some lockers. the time you need for installing it is nearly the same.

Explain this statement. I'm sorry I don't speak freaky deaky dutch :D

He means you don't want to over gear so that when you are in 6th your RPM won't be too low that it does nothing.

OK but with lower gears i.e. 4:11 or 4:56 wouldn't the rpm's be higher? Like say 60mph in 6th gear with 3:07 gears at 2000rpm would be 4000 rpm's in 6th gear with 4:56 gears right?
